# glob-stream

[![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] [![Build Status][travis-image]][travis-url] [![AppVeyor Build Status][appveyor-image]][appveyor-url] [![Coveralls Status][coveralls-image]][coveralls-url] [![Gitter chat][gitter-image]][gitter-url]

A [Readable Stream][readable-stream-url] interface over [node-glob][node-glob-url].

## Usage

```javascript
var gs = require('glob-stream');

var readable = gs('./files/**/*.coffee', { /* options */ });

var writable = /* your WriteableStream */

readable.pipe(writable);
```

You can pass any combination of glob strings. One caveat is that you cannot __only__ pass a negative glob, you must give it at least one positive glob so it knows where to start. If given a non-glob path (also referred to as a singular glob), only one file will be emitted. If given a singular glob and no files match, an error is emitted (see also [`options.allowEmpty`][allow-empty-url]).

## API

### `globStream(globs, options)`

Takes a glob string or an array of glob strings as the first argument and an options object as the second. Returns a stream of objects that contain `cwd`, `base` and `path` properties.

#### Options

##### `options.allowEmpty`

Whether or not to error upon an empty singular glob.

Type: `Boolean`

Default: `false` (error upon no match)

##### `options.dot`

Whether or not to treat dotfiles as regular files. This is passed through to [node-glob][node-glob-url].

Type: `Boolean`

Default: `false`

##### `options.silent`

Whether or not to suppress warnings on stderr from [node-glob][node-glob-url]. This is passed through to [node-glob][node-glob-url].

Type: `Boolean`

Default: `true`

##### `options.cwd`

The current working directory that the glob is resolved against.

Type: `String`

Default: `process.cwd()`

##### `options.root`

The root path that the glob is resolved against.

__Note: This is never passed to [node-glob][node-glob-url] because it is pre-resolved against your paths.__

Type: `String`

Default: `undefined` (use the filesystem root)

##### `options.base`

The absolute segment of the glob path that isn't a glob. This value is attached to each glob object and is useful for relative pathing.

Type: `String`

Default: The absolute path segement before a glob starts (see [glob-parent][glob-parent-url])

##### `options.cwdbase`

Whether or not the `cwd` and `base` should be the same.

Type: `Boolean`

Default: `false`

##### `options.uniqueBy`

Filters stream to remove duplicates based on the string property name or the result of function. When using a function, the function receives the streamed data (objects containing `cwd`, `base`, `path` properties) to compare against.

Type: `String` or `Function`

Default: `'path'`

##### other

Any glob-related options are documented in [node-glob][node-glob-url]. Those options are forwarded verbatim, with the exception of `root` and `ignore`. `root` is pre-resolved and `ignore` is joined with all negative globs.

#### Globbing & Negation

```js
var stream = gs(['./**/*.js', '!./node_modules/**/*']);
```

Globs are executed in order, so negations should follow positive globs. For example:

The following would __not__ exclude any files:
```js
gs(['!b*.js', '*.js'])
```

However, this would exclude all files that started with `b`:
```js
gs(['*.js', '!b*.js'])
```
